    - CVE-2026-56131: lack of handler call depth tracking for calls to XML_ResumeParser from within       handlers in cases of a policy violation (bsc#1268572).
    - CVE-2026-56132: heap-based buffer overflow in doProlog in xmlparse.c (bsc#1268573).
    - CVE-2026-56403,CVE-2026-56404,CVE-2026-56405,CVE-2026-56406,       CVE-2026-56407,CVE-2026-56408,CVE-2026-56409,CVE-2026-56410,       CVE-2026-56411,CVE-2026-56412: multiple integer overflow vulnerabilities (bsc#1275115).

    - CVE-2026-76957: lack of handler call depth tracking with custom encoding callbacks. Thus, a use-       after-free can occur (bsc#1275859).
    - CVE-2026-77214: out-of-bounds read due to insufficient checks in `XML_ParseBuffer()` (bsc#1284334).
    - CVE-2026-93990: fails to validate low surrogates following high surrogates in UTF-16 input     (bsc#1282347).
    - CVE-2026-102633: Denial of Service via integer overflow in expat_realloc (bsc#1283493).

    Update to 2.8.5 (jsc#PED-16154):

     * Bug fixes:
     * Fix an OOM-related memory leak on a failed overflow check
     * Fix memory alignment for architectures with 128bit pointers
     * Mark XML_SetHashSalt deprecated
     * CMake: only add /source-charset:utf-8 when /utf-8 is not present
     * lib: resolve undefined behavior from overshifting a signed int
     * lib: support read-only hash table lookup with non-zero-terminated      keys
     * lib: use a C99 bool for ENTITY.open
     * version info bumped from 13:3:12 to 13:4:12
     * fix support for 2+ GiB documents (regression from 2.8.2)
     * reject empty version in the XML declaration
     * fix printf format for AIX
     * CMake|AIX: enable EXPAT_DEV_URANDOM by default
     * version info bumped from 13:2:12 to 13:3:12
     * Existing API function XML_SetHashSalt is now deprecated
     * because of its limitations, and its use should be
     * considered a vulnerability. Please either use the new API
     * function XML_SetHashSalt16Bytes (with known-high-quality
     * entropy input only!) instead, or leave the derivation of
     * a 16-bytes hash salt from high quality entropy to Expat's
     * internal machinery (by *not* calling either of the two
     * XML_SetHashSalt* functions).
     * xmlwf: Fix a memory leak
     * WASI: Fix format specifiers for 32bit WASI SDK
     * Fix a class of false positives where input should have been        rejected with error XML_ERROR_ASYNC_ENTITY; regression from        earlier security fix (of Expat 2.7.0)
     * Prove and regression-proof absence of integer overflow      from function expat_realloc
     * Remove 'harmless' cast that truncated a size_t to unsigned
     * xmlwf: Resolve use of functions XML_GetErrorLineNumber        and XML_GetErrorColumnNumber
     * CVE-2025-59375 -- Disallow use of disproportional amounts of        dynamic memory from within an Expat parser
     * xmlwf: Fix (internal) help generator
     * xmlwf: Mention supported environment variables in
